Scientists videotape brain’s thoughts

Scientists at Berkeley may not only be able to read your mind, they may be able to see what’s in it, too.

In a study published this week in Current Biology, the researchers showed video clips to volunteers, then measured their brain activity with an MRI .

Here’s an example of what the people watched vs. what their brains revealed:

It could become a powerful tool to communicate with people who cannot verbalize, such as stroke victim and coma patients, Scientific American says. Unfortunately, it’s several decades away from being perfected for that use.

    Cool stuff. What is not several decades away are several non-invasive methods to substantiate truth from lies. What is stopping us from using them in court? The joy of the dramatic proceedings? The criminal lawyers lobby? The fear of science?

    A bit misleading:

    The image on the right is actually reconstructed video clips based on a database of youtube videos. The algorithm compares the brain activity with its database and tries to reproduce clips based on small (about 1 second) samples of data. It’s not what’s in people’s minds, but a program’s prediction of which sets of clips might have produced images causing the activity it sees in the brain.
